Manufacturer lifecycle
Product overview
RG-S5750-24SFP4XS24DP-UP is Ruijie’s building-side all-optical aggregation switch for the Power over Fiber (PoF) solution. The faceplate combines 24 × 1G SFP optical downlinks, 4 × 1G/10G SFP+ uplinks, and a DB78 interface that feeds hybrid cables carrying both optical data and electrical power.
Official Ruijie materials list up to 100 W per hybrid output and up to 2400 W system-level output when power modules support that load. This is not a copper RJ45 PoE+ access switch — optics and hybrid cabling are mandatory.
Manufacturer end-of-sale notices apply (international EOS 2025-07-10; China EOS 2025-07-30). RFQs remain appropriate for legacy sourcing verification, replacement planning, or alternative-model guidance — without assuming stock, condition, or warranty.
PoF power & configuration
Hybrid-cable power (PoF)
- DB78 power interface feeds hybrid cables that carry optical communication and electrical power together
- Up to 100 W per hybrid-cable output on authorized Ruijie materials
- Up to 2400 W system-level output when the chassis is populated with suitable power modules
- Maximum budgets are configuration-dependent — do not assume every quote delivers 2400 W
What PoF is not
- Not a conventional 24-port RJ45 IEEE 802.3af/at closet PoE switch
- Downlink optics and hybrid cable plant are required design inputs
- IEEE 802.3af/at-compatible power management modes may be listed for PoF control — that does not convert the faceplate to copper PoE
Power modules
- Up to three modular PSUs on Ruijie materials; paralleled modules must be the same model
- Confirm PSU PIDs and hybrid drop wattage on the RFQ

Deployment scenarios
Campus buildings already committed to Ruijie PoF hybrid cable plants that still need verified legacy hardware.
All-optical aggregation closets where remote endpoints are powered over hybrid fiber, not copper PoE runs.
Replacement or expansion planning against Ruijie’s published EOS dates and listed successor families.
Technical selection notes
Confirm hybrid drop count (≤24), per-drop wattage (≤100 W), total PoF budget vs installed PSUs, uplink optics, and VSU intent. Treat manufacturer EOS dates as region-specific. Do not treat a standard SFP aggregation switch as a drop-in PoF replacement — hybrid power delivery is part of this PID’s role.
Not recommended for
Not a copper RJ45 PoE access switch.
Not appropriate when hybrid cable plant is not approved.
Not a 100G data-center leaf.
Not a guarantee of new sealed manufacturer supply after EOS.

FAQ
Is RG-S5750-24SFP4XS24DP-UP end of sale?
Yes. Ruijie published EOS for this PID: international market 2025-07-10 (last support 2030-07-10) and China market 2025-07-30 (last support 2030-07-30). See Ruijie official EOS notices.
Does EOS mean QianliSwitch has no units?
No. EOS is the manufacturer sales status. Independent suppliers may still source verified used/refurbished/legacy inventory — or none. Condition and availability are confirmed only on RFQ.
Is PoF the same as RJ45 PoE?
No. PoF uses hybrid fiber cable carrying optical data and electrical power via the DB78 interface. The 24 SFP ports are optical business ports, not copper PoE ports.
What ports does this PID provide?
24 × 1G SFP optical downlinks, 4 × 1G/10G SFP+ uplinks, plus DB78 hybrid power outputs for up to 24 hybrid cables.
Does every configuration deliver 2400 W?
No. 100 W/output and 2400 W system figures are maxima on authorized materials and depend on installed power modules and the hybrid load plan.
Can a standard Cisco SFP switch replace this PoF model?
Not as a functional drop-in. A standard SFP aggregation switch does not provide Ruijie hybrid-cable PoF power delivery.
What should an RFQ include after EOS?
Exact PID, region, condition preference, hybrid drop/watt plan, PSU needs, optics, quantity, and whether you want alternative-model guidance instead.
